Broader description: The PERICLES Content Aggregation Tool (PeriCAT) is a framework for Information Encapsulation techniques. It integrates a set of information encapsulation techniques from various domains, which can be used from within the framework. Furthermore PeriCAT provides a mechanism to capture the scenario of the user, and to suggest the best fitting information encapsulation technique for a given scenario. PeriCAT integrates 15 different information encapsulation techniques from 7 domains:

• Packaging
  • Simple archive formats with optional compression
    • ZIP
    • tar
  • Structured Packaging
    • BagIt
  • Using metadata schemata together with a simple archive format
    • METS SIPs
    • OAI-ORE SIPs
• Embedding
  • Digital Watermarking
    • QR Codes
  • Steganography
    • F5
    • OpenStego LSB
    • OpenStego random LSB
  • Use of file format features
    • JPEG text adding
    • PDF file attacher
    • PNG chunk adding
  • Information frames
    • Image-Image frame expanding
    • Image information embedding using a steganography frame
    • Text information frame
